Inhigh-hysteresis analog triggering mode, the trigger is generated when the
signalvalue is greater than highValue ,with the hysteresis specified by
lowValue.
Figure3-12. High-HysteresisAnalog Triggering Mode
Inlow-hysteresis analog triggering mode, the trigger is generated when the
signalvalue is less than lo wValue, with the hysteresis specifiedby
highValue.
Figure3-13. Low-HysteresisAnalog Triggering Mode
Theanalog trigger circuit generates an internal digital trigger based on the
AIsignal and the user-defined trigger levels. This digital trigger can be used
byany of the timing sections of the DAQ-STC, including the AI, AO, and
general-purposecounter/timer sections. For example, the AI section can be
configuredto acquire nscans after the AI signal crosses a specific
threshold.As another example, the AO section can be configured to update
its outputs wheneverthe AI signal cro sses a specifict hreshold.
